Certified quality

Both our operating processes and our products are tested and certified by various bodies. We are certified in accordance with ISO 9001:2008, the Pressure Equipment Directive PED 97/23/EC Module H. and FIRE-SAFE. We were one of the first industrial valve manufacturers to meet the environmental requirements of TA Luft. We also have Russian approvals such as GOST, RTN and for Gazprom.

Customer-oriented special solutions

We continue to develop our industrial valves such as butterfly valves, shut-off valves and regulators in close consultation with our customers. Based on successful reference installations, we optimise industrial valves to meet the respective customer-specific requirements. The result: precisely fitting valves – even for special applications.

Wide product range

In order to be able to guarantee a perfect fit for a wide range of industries, we have an extensive product range: industrial valves with nominal diameters up to DN 4000, pressures up to over 200 bar and temperature ranges from -196 °C to + 1300 °C are proof of this. Other products from our portfolio include butterfly valves and special valves.

State-of-the-art technology

The valves have defined the state of the art for years. For example, we use triple eccentric discs and manufacture with carbon steel or stainless and acid-resistant steels as well as special materials. We achieve solutions that previously seemed unfeasible.
